3 April, 2009 - We are pleased to announce that access to INIS [International Nuclear Information System] database has been now opened to all Internet users around the world. Free, open and unrestricted access is available from the INIS Homepage (http://www.iaea.org/inisnkm), or directly from the following link: http://inisdb2.iaea.org
This initiative provides easy access to reliable nuclear information on the peaceful uses of nuclear science and technology, including nonconventional literature, and makes nuclear knowledge readily available worldwide.
Established in 1970, INIS represents the world's largest database of scientific and technical literature on a wide range of subjects from nuclear engineering, safeguards and non-proliferation to applications in agriculture, health and industry.
Currently, the INIS Database contains over 3 million bibliographic records and almost 200,000 full-text nonconventional documents, consisting of scientific and technical reports and other non copyrighted information.
